I don't worry about the people and groups who latch onto a set of standards or styles or best practices and enforce them with sticks and goads. They won't find much success, and it doesn't matter who suggests styles or standards. Their inflexibility will hurt them more than anything else, and there's nothing we can do for them until they fix that problem.

I see no reason not to suggest good practices for everyone else, though, especially as they're gaining experience and good taste until they reach the point where they can evaluate their options and customize what they do for their current situations.

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
